#37
What I simply don't understand is the reason why one lens (Tamron 200-500) is tested on APS-C and the other lens, which has the longer focal length, has to be done on fullframe. Now, if 500 is good for APS-C, why not 600? Too much of a distance to the target?

 

Other way round: Tamron says, "Di" in the lens' name is for APS-C and full frame. So, both lenses are also usable for fullframe, or I'm misunderstanding some texts of Tamron. Either way, it doesn't make much sense to compare those lenses when one was shot with APS-C body and the other fullframe. And it was the reply for the question a couple of posts ago which puzzled me.

 

But there's no need to continue. I can live with being puzzled  :blink:

 

Anyway, have fun with testing the lens. As far as I'm concerned I find lensrentals a reliable source for information about resolution of lenses and the comparison Roger already did could be enough for me to choose one of those candidates. Okay, they don't tell much about vignetting, but they usually test a whole bunch of the same lens which also gives interesting information.
